Q1. A big olive (m = 0.082 kg) lies at the origin of a xy coordinate system, and a big Brazil nut (M = 0.50 kg) lies at the point (0.92, 2.1) m. At t = 0, a force o = (3.5 + 1.6) N begins to act on the olive, and a force n = (-3.9 -3.0) N begins to act on the nut. What is (a) x and (b)y displacement of the center of mass of olive-nut system at t = 5.1 s, with respect to its position at t = 0
